Sending SMS to landline numbers

You cannot send SMS to a landline destination number: the Twilio REST API will throw a 400 response with error code 21614, the message will not appear in the logs, and the account will not be charged.

Best practices

Dynamic alphanumeric sender ID is supported but numeric sender ID will be attempted on a best effort basis. We highly recommend sending with an alphanumeric sender ID specific to your brand and content.

Twilio strongly encourages customers to review proposed use cases with qualified legal counsel to ensure they comply with all applicable laws. The following are some general best practices:

  1. Get opt-in consent from each end user before sending any communication to them, particular for marketing or other non-essential communications.
  2. Only communicate during an end user's daytime hours unless it is urgent.
  3. SMS campaigns should support HELP/STOP messages, and similar messages, in the end user's local language.
  4. Do not contact end users on do-not-call or do-not-disturb registries.

The Nigerian Communication Commission has mandated telecom operators in Nigeria to implement the Do-Not-Disturb (DND) registry. The Do Not Disturb service in Nigeria allows customers to opt out of receiving promotional messages. Any attempt to send promotional SMS to those numbers will fail. Twilio provides special routes that have permission to contact phone numbers on the DND list by SMS when the traffic is classified as OTP (one-time password). 1. Unsolicited messages are not allowed via this route. Your recipients must have expressed permission to be contacted via SMS. 2. A phone number on the DND list might also be switched off, out of network coverage, or simply dead. The delivery report will indicate the status of messages sent to phone numbers on the DND.
